A Study to Determine if Technosphere® Inhalation Powder (FDKP) Causes ECG Changes (QTc) Following the Medication's Inhaled Administration.

A Phase 1, Randomized, Double-Blind, Cross-Over, Placebo- and Active-Controlled Cardiac Safety Study of Therapeutic and Supratherapeutic Doses of Fumaryl Diketopiperazine Administered as Technosphere® Inhalation Powder in Healthy Subjects

48 healthy adult male & female subjects will be enrolled in this study to determine the effect of Technosphere® Inhalation Powder (FDKP) on the QT interval of the EKG. Eligible subjects will be randomized into a dosing regimen after admission.

Study Overview

• Status: Completed
• Conditions: Healthy Subjects
• Intervention / Treatment: Drug: Technosphere Inhalation Powder (FDKP); Drug: Moxifloxacin; Drug: Technosphere Inhalation Powder (FDKP); Drug: Placebo

Detailed Description

This is a Phase 1, randomized, double-blind, cross-over, placebo- and active-controlled cardiac safety study in 48 healthy subjects (both male and female subjects) designed to assess the effect of FDKP on cardiac repolarization, if any, following introduction of Technosphere® Inhalation Powder via inhalation. Each trial subject will be administered 20 mg of FDKP, 40 mg of FDKP, 400 mg oral dose of moxifloxacin (active), and placebo in a crossover design during an 11 day in-patient stay.
